Benefits of technology

[0012] Another object of the present invention is to provide such a prosthesis which is relatively inexpensive to manufacture.
[0013] Yet another object of the invention is to provide such a prosthesis which can provided in a very compact form, and which can be easily manipulated and installed in a minimally invasive procedure.
[0015] Yet another object of the invention is to provide a small number of hernia repair methods which can be used for repairing a wide variety of hernias.
[0018] Still further, it is preferred that the flexible mesh material may be formed of propylene or other suitable materials, the central portion will have an enhanced strength, such as being formed of two layers of the mesh material, and for the prosthetic element used to repair abdominal hernias, the central portion will also be stretchable to absorb greater forces imposed thereon.

Problems solved by technology

Hernias are common medical problems involving a protrusion of an organ or body part through a rupture in connective tissue or through a wall of a cavity in which is normally enclosed.
To date, no single technique employed for hernioplasty can be performed for all the classifications of hernia within the groin, but instead individualized hernioplasties are required for variability of location of hernia and size hernia sac and defects, as well as other associated complications of incarceration and strangulation.
Some complications associated with use of conventional mesh prostheses include shrinkage, migration and erosion of adjacent tissue by the prostheses, as well as formation of seroma, which is collection or trapping of body fluids near the repaired area and may lead to infection.
Unfortunately, even with the significant advancements over the years, recurrence still remains a very significant problem.
This is so even with the shift towards individualization of hernia repair, which complicates the overall treatment procedure.

first embodiment

[0024] First Embodiment

[0025] Referring now to FIG. 1, a plan view of a hernia repair mesh prosthesis in connection with a first embodiment of the invention, particularly related to repair of groin or femoral hernias, is shown generally at 1. The prosthesis 1 is a substantially planar member formed of polypropylene mesh or other appropriate material(s), and is universally suitable for herniorrhaphy for all levels of groin hernias, including direct, indirect, sliding, femoral and recurrent hernias. Throughout the present specification, a number of relative positional terms such as upper, lower, and side are used to illustrate parts of the prosthesis 1 in the orientation thereof shown in the drawings. These terms are used for purposes of illustration rather than limitation, and as such, are not intended to be fixed and absolute. The reader will realize that the prosthesis could be inverted, folded, or placed in a different orientation than the one shown, and that after such modificati...

second embodiment

[0038] Second Embodiment

[0039] Referring now to FIGS. 2-4, there is shown a hernia repair mesh prosthesis 100 according to a second embodiment of the invention, particularly related to repair of abdominal wall hernias or ventral hemiorrhaphy. FIG. 2 is a plan view of the prosthesis 100, FIG. 3 is a side elevational view of same, and FIG. 4 is an enlarged, sectional view of a stretchable portion of same. Like the prosthesis 1 of the first embodiment, the prosthesis 100 is a substantially planar member formed of polypropylene mesh or other appropriate material(s), although it is distinct from the prosthesis 1 in several significant aspects.

[0040] The prosthesis 100 preferably includes a substantially rectangular, main, central portion 103 which actually covers the hernia rupture to be repaired, and a number of support portions or flaps 105, 107, 109 and 111 integrally connected around the periphery of the central portion 103. The prosthesis 100 further includes suture type reinforceme...

Abstract

A hernia repair prosthetic element includes: a central portion which covers a hernia opening within a patient; plural support portions integrally connected about a periphery of the central portion for securing the central portion in covering relation to the hernia opening; the prosthetic element, including the central and support portions, being a substantially planar member formed of flexible mesh material; the support portions being foldable relative to the central portion so that the prosthetic element can be selectively manipulated between folded and unfolded shapes; the support portions being adapted to securely engage various components of the patient's body surrounding the hernia opening; and openings are formed through the central portion for passage of fluid therethrough. The prosthetic element has only two basic shapes, one for use in relation to all groin hernias and one for use in relation to all abdominal hernias. The flexible mesh material may be of propylene or other suitable materials, the central portion has an enhanced strength, such as being formed of two layers of the mesh material, and the central portion may be stretchable to absorb greater forces imposed thereon.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to novel hernia repair mesh prostheses, and to methods of using same to repair hernias. More particularly, the present invention relates to such prostheses which drastically reduce hernia recurrences and which are relatively simple to construct and install, and to methods of using same.[0003] 2. Background Art[0004] Hernias are common medical problems involving a protrusion of an organ or body part through a rupture in connective tissue or through a wall of a cavity in which is normally enclosed. Some known types of hernias are in the groin area, including direct, indirect and femoral hernias, and others are in the abdominal wall.[0005] Medical devices and procedures for repairing hernias are widely known, and have been reported well over one hundred years ago, and treatment of hernias has gone through incremental improvements over time, including the early work of A. P. Cooper, The Anatomy And Surgical Treatment O...
